September 15, 1926.

This invention relates to back cushions; and it comprises a spring cushion having a border frame braced by a plurality of trans verse bars to which a series of springs are aiiixed for holding a cover for the cushion taut, the cover being wrapped around the border frame and held in permanent position thereon by a clamp which extends around or substantially around the frame, the said clamp being recessed at intervals along the upper and lower longitudinal edges of the frame; a )lurality of clips hingedly mounted on the border frame in the recessed portions of said clamp and provided with means for detachably securing them to a surface upon which the back cushion is to be mounted.

In the construction of motor vehicles back cushions are sometimes mounted so as to be removable if occasion should arise, but they are more often permanently mounted so that their removal for replacement or repair is difficult and expensive. It is, accord ingly, an object of my invention to provide a. durable and inexpensive structure which permits of ready removal of the back cushion yet which, in use, is hidden and does not detract from the neat and finished appearance of the cushion.

A further object of my invention is to so mount a back cushion that it can be easily removed from its support for replacement or repair, the fastening means being normally hidden but accessible when the cushion is swung upwardly.

A still further object is to removably mount a back cushion so that its upper edge is hingedly mounted on support therefor, the hinge being hidden when the cushion is in use, and the lower edge being fastened to the support by means which is hidden, in use, by a seat cushion other and further objects will be apparent from the following description and drawing, in which Figure l a vertical sectional view taken through the cushion back and support. showing the means for attaching the cushion to the support alon its upper and lower edges.

Serial No.

Figure l: is a vertical sectional view taken through the cushion back and support, showing a modilied form of attachment.

Refer more particularly to the drawmgs:

A border frame 1 is bridged by a plurality of transverse bars 2 which are arched inwardly of the cushion and upon which are mounted a plurality of springs 3 for holding a cover f taut. The cover is wrapped around the border frame and held in permanentposition thereon by a clamp 5. This clamp may be of any desired form, but is advantageously serrated along one of its edges to thereby provide a plurality of spaced teeth for gripping the cover material and holding it in place on the frame. his formation of the clamp, moreover, permits of bending it atthe corners of the frame without producing a bulging or bunching of the metal so that it can extend entirely around the frame a continuous strip. The invention, however. is not limited to this specific form of clamp since .it is obvious that it could be of any desired shape, or in a plurality of sections without affecting the mounting of the cushion upon its support. Q

The clamp 5 is cut away at intervals along the upper and lower edges of the border frame, as at 6. for the reception of the fastening clips Each of these comprises a metal strip bent upon itself to encircle the borderct'rame of the cushion, and is formed with a hole through which a screw or bolt 8 is passed for attaching it to a supporting surface 9.

To mount the back cushion it is supported in substantially horizontal position and the clips which are along the upper edge of the cushion are fastened to the supporting surface. The cushion is then swung downwardly into the position which it occupies in use. thus hiding the clips which hold it in place along its upper edge and presenting a neat and finished appearance. The clips along the lower edge of the frame are then fastened to the back support, these latter being hidden in use of the back cushion by the seat cushion with which it is associated.

A modified form of attachment is shown in Figures f and 5 wherein the clips 10, along the lower edge of the cushion are directed inwardly of the cushion frame, and-thus are completely hidden by the cushion when it is in place upon the supporting surface 9. In mounting the cushion in place upon its supporting surface the clips 7, along the upper edge of the cushion are fastened by means of screws 8 or bolts, the cushion being held in horizontal position. After fastening the clips along the upper edge of the frame the cushion is swung to vertical position, the clips 10 are turned inwardly, and the bolts 11 which are carried by the clips are extended through holes in the support 9. The nuts 12 are then tightened to hold the lower row of clips in position. Thus, the back cushion is fastened along its upper and lower edges and is securely held in place by clips which are hidden by the cushion in its mounted position.

From the foregoing it will be apparent that I have provided a back cushion which is removably mounted by means which is of simple, durable and inexpensive construction, hingedly mounting the cushion so that the said means is hidden and inaccessible when the cushion is in use, but readily detachable from a support when the cushion is swung to-a position to uncover it.

What I claim is t 1. A back cushion comprising a border frame, transverse bars extending thereacross, springs mounted on said transverse bars, and a cover held taut by said springs, clamping means associated with said border frame for permanently retaining said cover in position thereon, said clamping means being notched at intervals to expose said border frame, a plurality of clips encircling said frame in the notched portions of the clamping means, and fastening means for the said clips for attaching them to a supporting surface whereby said cushion will be hingedly mounted 011 said surface.

2. A back cushion comprising a bottom border frame adapted to be fastened to a support in a substantially vertical plane, hinge supporting members for said cushion encircling the upper and lower edges of said frame, said supporting members each comprising a continuous element formed with a circular portion rotatably surrounding the frame and two superposed and coextensive flat portions extending therefrom, said flat portions having aligned apertures formed therein, said supporting members being adapted to have the fiat portions thereof extended downwardly and to be fastened to said support by means passing through said MAURICE srnsmrz.
